' To. all whom it may concern:

specification;

My invention which relates generally to' means combined with engines in;the nature of safety blow oil's, more particularly hasfor its object toprovide i -new and imroved applia'nce, more especially adapted Be. itknown that I, JULIUS P. FELL,

residing at Berclair, in the county of Groliad nd. State of Texas, haveinvented a newand -Improved Gombined- Safety-Valve and Waste-Cock, ofwhich the following is a or use 1n connection with the water,.or cooljing jackets of internal combustion engines,

and it comprehends,.generally, a new article that can be easily-attachedto and placed in communication with the water jackets of the engine andadapted to be hand manipulated andadj'usted so it will readily act aswaste or drain cock and in which a sup-,-

p emental ex ansible fluid actuated means is embodied or automaticallyopening the fluid in the jacket to atmosphereas the same begins to go tothe freezing point.

I My invention also comprehends as'a new article of manufacture, atubular member carrying means for locking upon and communicating'withthe water jacket of an engine, a closure member normally held to close011 the tubular member from atmosv ghere and another" means operableunder uid expansion for lifting the closure-mom her-at tunes. 'F'LI Inits more subordinate featuresgmy in,- vention consists of thepeculiar'arrangement be hereinafter fully described, 'specificall ointedout in the appended. claims an illustrated, in in which':=-

' Fi re 1, is a view of so much of anin-Z terna combustion enginenecessary to illustrate the practical application thereto of myinventlon, Fi 2, is a vertical section:

of my-invention', s owing the same in con nection with the water' jacketof the engine the parts being in their closed or normai' position.Figrflg isa similar view showing upper end of which is threaded as at aCOMBINED SAFETY-VALVE AN 1 WASTE COCK.

Patented Apr, I 1910.

whereby it can be convenientlyfs'eeured in a threaded aperture 10 in thewater jacket wall mwhich, in practice, is tap ed through the said wallat the point it is esired to attach, my inyent-ion the upper end of thej member A, having anut portion; B below the threaded shank; to receivea.- wrench. or other clamping tool for securing the member A in,position, on' thewater jacket aswill beclearly understood firom thedrawing,- by reference,-

to Figs. 2 and. 3. ofwliich it will; be seen; the

forms the overflow or waste cock. K' represents a'tube like cup of verythin copper or brass, that mounted in a bracket L that. rojectslaterally from the member. A and s idable over the cup K-is an invertedtubularcup J also of very thin brass or cop ier that telescopicallyrideson the inner tu e or cup K 1n the manner clearly shown-in thedrawing. e

F indicates a lever that is fulcru'med at f on the lower end of astandard Lthat extends perpendicular from the bracket L and whichcarries a closure ca f that is normally heldoon andcloses t e open. enda of the tube A by a stout coiled spring. E fastened at one end to thebracket L, its other enddetachably engaging'a hooke on the lever E, thelatter havinga knob f at the 'outerend whereby it can be readily pulleddown by hand to uncover the'end a of the tube when the spring E isdisconnected from the hook c. Q 7 1 Cu ,J has a knob G that engages thelever B and which forms afhand-hold for pulling lowe'r'en d of themember A'is open and it p the cup J from the'cup K when the lever F isswungback as will presently more'fully the accompanying drawings,

appear.

lained as followszThe tubular cup K is ed with water-and is closed bythe tube J which telescopically en ages the same and isi helddown IE thelever F and tlief'spring the lever also closing the tube or' waste cockfrom the water jacket. The tubes" K and J being of a'much thinner metalthan rate Ayand more exposed, the water therein will freeze prior to thewater in the tube A" and by reason thereof the ex ansion in tube Klowers the tube J where ob G-engages and lifts the lever F- that acts asa valve, from the tube A to-al low the water'in. the tube A to waste andprevent the freezing thereof in the water he manner" in which my.invention oper ates is best e the weig t of jacket and the danger ofsaid jacket burstingl The knob G,'it should be stated, is adjustablymounted on. the tube J to operate quickly or slowly on the lever F, thesaid knob G-also forming the lift for removing the member J from cup- Kwhen it is desired to fill the latter, it being understood that whenthis is desired the spring E is detached.

While I have shown my improvement as a plied to the water jacket ofanengine, it is 0 vious it can be as readily adapted for use on theradiator of an automobile.

Having thus described my invention, what I claim 1s:

1. A means for protecting water jacketed cylinders, comprising an outletadapted to be tapped into the water jacket, a bracket on the-outlet, avalve hinged to the bracket, means for swinging the valve to close overthe outlet and a fluid holding member having a portion that extends asthe fluid in the holder expands and engagingthe valve decutoff the valveopening, a spring for holding the lever closed, a uid holder mounted onthe bracket that includes two telescopically mounted members, the loweror expansible one of -which engages the lever valve to lift it", thevalve also having a lift-.

ing rod provided with a finger piece.
